Abstract

Aparato de tubo de rayos catódicos del tipo de refrigeración por líquido. Se puede evitar una degradación del contraste causada por la luz dispersa generada en un aparato de tubo de rayos catódicos del tipo descrito incorporado en un aparato de televisión del tipo de proyección. La luz dispersa (7) emitida desde una pestaña (borde periférico) (11a) de una lente (11) fuera de un acoplador (10) y la lente (11) dispuesta en la cara frontal de un tubo de rayos catódicos (1) de un aparato de tubo de rayos catódicos del tipo de refrigeración por líquido (5) es apantallada por miembros (nervios) de apantallado de la luz (20), (20a) dispuestos en el acoplado (10) y/o en una placa de lente (13). Figura 2.
